For anyone not into being given commentaries from high horses (I name no names), here's a quick rundown.
First, I agree that using all caps in a careless manner is not polite. Save it for things actually worth the shouting.
Second, if rumors on f95zone are to be believed, Phalzyr's wife passed away. That's allegedly what happened to him, and he has understandably decided to take a break from porn games as far as we know. It is unfortunate I know neither him nor more details about his life to have more information to offer you.
Finally, I think we are generally in agreement that we hope he will return...someday.
Edit: I just went to the front page of this very thread and took a look at Phalzyr's Patreon page. It is empty. I checked the comments and it seems the page has been closed down entirely, the only thing that remains being Phalzyr's personal account.
I do not want to jinx things, but it seems the possibility of Phalzyr's return is slim. Perhaps we should focus efforts more on replacing him, if we cannot reliably reach out to him, whether it be to offer our sympathies or to attempt to persuade him to return.
